Feature request: display real IP, when working behind proxy

[Orbit173]

When using Nginx in reverse proxy mode (client->nginx wss->ygg ws), a local IP is displayed in the client list.
Can you add the processing of the "X-Real-IP" header from Nginx, when working on the sceme "ws" ?

Ideally it should parse X-Forwarded-Host header and/or Forwarded header before X-Real-IP since the later is a convention and the former is a standard.

IMO better to use fd passing, but this will limit applicability to Linux only. It could be implemented as an extension to admin's addPeer command.

Unfortunately, a proxy supporting fd passing to upstream is hardly exist.
